Python 3.2.1 to be exact. What is required to make it possible on Android?

[Robbie Matthews]

Yeah. This is a non-trivial project, but worth discussing.

Someone needs to work out how to crosscompile python 3 for an ARM platform.

Thing is why would we want that?

Py3 isn't much supported yet, many libraries are not compatible, and that's
what makes Python strong it's "batteries" why do we want Py3 on Android now
if we can't get batteries.

If you have a resonable why I can take a look and what it takes.

We want it because syntax parsing for Python 3 is simplified. There are
less syntax sugar constructs, and thanks to that performance should be
greater.

As a side effect - if some package has ported to Python 3, that means it is
active, and its developers are probably interested to test it on their
Android devices. I don't know how to cross-compile Python 3 for ARM, but if
it is possible to cross-compile PyPy, then the efforts to Python 3 porting
can be joined.

yes I know py3, but that argument is not totally valid.

For example Django which is one of Python's largest web frameworks is not
py3 compatible officially, there's a port, but not the official version.

Main development is been done for py 2.7, as everyone is waiting the others
to port they're applications.

You could try mimicing what I did for py2 to get py3 into Android, but
again, I'm not sure if it makes much sense, as it breaks the API and
renders some packages useless.

Do you really expect users running Django apps on Android any time soon?
I'd say they will be more interested to run Blender on their Honeycomb
tablets.

Well I do use Django apps on Android, and I'm releasing a production ready
application based on Twisted soon. I don't really think we will see Blender
on Android any time soon, I guess gtk or qt are dependencies. Still go
ahead, do the port, I would like to help you, but don't expect me to do it
(and I'm talking just for me here) unless I really need it.

Blender is OpenGL rendered. No GTK or Qt. Just want to stress that starting
with Python 3 on alpha platforms is more beneficial for users as it gives
them ability to write tutorials in a consistent language early. Many
libraries can be run with 2to3 and it is a goal to catch early if they
can't.

I think that we really need Python 3.X.
Why? For example, let's look at me. I'm learning Python. And I use P3.2.
And I know there are many differences for 2.X versions.
I'm not the only one, who have same request - to develop using Python. I'm
not newbie on developing - have 3 years Delphi using. I think last version
of language is thу best. That is why we really need python 3.2

[Robbie Matthews]

Yes, but are you willing to do the work?

Robbie

[Владислав Мазур]

I don't know how to port Python to Andoid.
But if I can help you... You know I have not code for Android, only for PC.
May be we can find some who can do this work?

It's not rocket science, but none of the main developers here are
terribly keen to embark on a Python 3 development.
Not right now, anyway.
* None of us are paid for this, this is all being done out of our
limited free time.
* We're not stopping... indeed, we encourage... others getting
involved on the programming side.
* The current build environment's a bit of a kludge... I'd like to go
back to a more traditionaly build, easier now since Android has made a
proper tool-chain available....but to a significant degree it means we
have to start all over with Python 3.
* I'm not convinced that Python 3 is stable yet. At any rate there
doesn't seem to be a rush to conver over to it.
It will happen sooner or later, but just at the moment it's looking like later.

Robbie

[Владислав Мазур]

Ok, I understand we will have Python 3.X later. Nice!

But I have question. I'm only learning Python. Please tell me why do you think 3.X is not stable yet?

It probably is reasonably stable. What I meant was, there doesn't seem
to be a mad rush towards adoption yet.

Writing applications for Android devices is a great, fun way to learn
programming and for that reason alone it's worth getting a new generation
of coders onto Python 3 now.

Python 3 is the future, don't get stuck in the past...

I agree with those above me, I started developing in python at the end of
the 2.7 era and decided to just jump to 3 and I know there is a large and
ever-growing group of us.

Same here, started learning Python 2.6/2.7 and then jumped to 3.2. I would
appreciate being able to code for 3.x on my Android phone.

it,and android?

I have partially port the Python 3.2 to Android, by manually applying the
P4A's patches to Py3's source code. Details in
http://www.klayge.org/2011/11/02/compile-boost-1-47-with-android-ndk-r6/.

I am currently developing in python 3(first version of py that I've tried)
and am look for a way to run apps on my phone. Seeing that all I know about
python code is in python 3, it would be nice if python 3 was supported,
otherwise I would just not develop for android until it WAS supported.

I would also like to have a fully functioning Python 3 version for android.
All of my University stuff in python is based on 3.0 >. I'm forced to try
and learn both versions on-the-fly and its difficult.

rjmatthews62 I'm taking a programming class to learn python and have to
download Python 3 along with Idle to run scripts. I came across this site,
and your download Python 3 for Android after almost giving up and thinking
I had to drop the class because I couldn't find a compatible version for my
Android device. Thanks so much!!! By the way, do you know the source, my
device is blocking the download because it says the source is unknown. Thx,

You need to turn on 'Unknown Sources' under Menu-->Applications.

You'll also need to have sl4a installed:
